Etymology: Choeroichthys: Greek, choiros = a pig + Greek, ichthys = fish (Ref. 45335).
More on author: Günther.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 0 - 6 m (Ref. 90102). Tropical; 35°N - 25°S
Indo-Pacific: East Africa to the Line, Society (Ref. 4281), and Gambier islands, north to southern Japan, south to Tonga.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 8.5 cm TL male/unsexed; (Ref. 9710)
soft rays: 4. Short-snouted; dark, blackish brown with small black spots and small white ocelli in parallel series along trunk, and some white speckles over the back (Ref. 48635). Males are characterized by vertical row of silver spots (Ref 1602).
Inhabits intertidal reef flats. Also found in seagrass habitats to few meters depth (Ref. 48635). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205). Males may be brooding at 4.6 cm SL (Ref. 30874). Seen in lagoons and seaward reefs in 0-6 m (Ref 90102).
